vide an improved connector-for the parts of aspring bed or seat. It consists inthe elements and featureszoflconstruction shown and described, as indicated in the claims.- In the'drawings: Figure '1 is a plan view of a portion of a bed spring containing this invention; a Fig. 2 is an enlarged detail'section at the line, 2-2, on Fig. 1,Ishowing the connector in side elevation, one'of'the forms in. which it may be embodied. f

Fig; 31s a section at the line, 3'-3,' on Fig.2. 3

Figs. 4 and 5 are side elevations of the two parts of which the connector is comprised.

Fig. 6 is a plan View of a portion of a bed or seat spring having a connector of a modified form.

Fig. 7 is a section at the line, 77, on Fig. 6 on an enlarged scale.

Fig. 8 is a plan view of the load-supporting spring with which one end of the con nector is engaged, and the two parts of the connector each shown in dotted line in the position relative to the spring for entering them upon the spring and in full line at the position fully engaged therewith and with each other.

Fig. 9 is detail section at the line, 99, on Fig. 7, view showing the two parts of the connectors fully engaged with each other and with the bed spring.

Figs. 10 and 11 are perspective views of the two parts of the connector.

Fig. 12 is a side elevation showing the manner of engaging the connector with the tie spring.

The drawings show a form of bed spring or seat spring which is familiar in its general character comprising vertically yielding main springs, 1, which it will be understood are helical coils, and a relatively small helical tie springs, 2, which are interlocked with each other by screwing one helix crosswise of the other, making a cross which has its .two' forms. 1 to 5 inclusive, each connector, comprises.

Specification of Iletters Patent. Patented J 11y 22', 1920,

fourfends positioned for being connected re- 1 spectively with the four springs, 1, 1,1, 1,

which form agroup aroundthe cross. This inventionrelates to the form and construct1on of the connectors, A, by which the ends of the helical tie springs are connected with the respectively adjacent load-supporting These connectors are shown in springs, 1.

In the form shown in Figs.

two parts, 3 and 4, each of which has'at one end an open hook or eye for engagingth coil of thespring' 1, .Th hooks eyes, 3 and- 4., have their openings in 0a; posite directions so that they are adapted to be hooked onto the coil of the. spring, 1, by hooking movement: in opposite directions about that coil, so that when both are hookingly engaged with the coil, the opening of each eye orhook'islapped and closed by the other. eye or "hook, and'by means of the two eyes or'hooks, the engaged coil of the spring, 1, is completely encircled] At the-opposite cnds'said parts, 3 and 4, have each a hook, designated respectively 3* and awe]: engaging' the coil: or coils of the tie spring, 2. These hooks, 3 and 4", are both turned in the same direction, so that when the two connector members, 3 and 4, having their eyes, 3 and 4 engaged with the coil of the spring, 1, are operated bodily as a unitary element, the same hooking movement,-that is, a movement in the same direction-will engage both the hooks 3 and 4 with the coil or coils of the tie springs. Intermediate other, as seen at 34, where the part, 3, whose eye, 3, opens downwardly for its engagement with the coil of the spring, 1, crosses under the part, 4, whose hook, 4, opens upwardly for its engagement with said coil of the spring, 1. Thus when the two hooks, 3 and 4 are engaged by their opposite hooking movements with said coil of the spring, 1, and swung about said coil to each respectively close the opening of the other, they come into stopped engagement with each other at the crossing, 34; and by this means the two parts, 3 and 4, are adapted to be operated unitarily to swing the connector bodily about its pivotal engagement by means of the eyes, 3 and 4 with the coil of the spring, 1, to engage the hooks, 3 and 4 with the coils of the spring, 2.

In the form shown in Figs. 6 to 12 incluthe coils of the 'llGllCZLltlQ'SPIiII shows in 'what manner the two. parts, 7 and 'sive, the eyes by which the two connector parts,which in this form are designated 7 and 8, respectively,-are engaged with the coil oft-he spring, 1, are helical in form, adapted to screw into eachother, turning about the coil of the spring, 1, with which they are both engaged. This engagement by screwing together performs the same 'functlon for interlocking the two parts, 7 and 8,

which is performed in the previously described form: by the parts crossing one above. the: other atEAL By this screwing engagel 11GIlt tl16 Opening of each eye isclosed by the interlap of the other in the helix ofthe first, and the disengagement of said two parts from the coil of the spring, 1, is rendered impossibleexcept by the complete rotation of one or the other, or half rotation of both in opposite directions, such rotation being scribed. Forsecurityof engagement of the connectors with thetie sprmgsand protection against disengagement by accidentalrotation of thetie springs which might unscrew them from the connectors, the end of the final coil of the tie spring is slightly bent rout of its true helical or spiral position,'as

-' seen in F ig'. 9, so as to" contract the path between said'end and the next coil or turn of the spiral or helix to a distance less than the 7 diameter of the wire forming the connector.

.This expedient is not claimed as a part of this invention, having vbeen previously employed in other connectors.

I claim 1. In combination with two members of a spring structure to-beconnected, a connector comprising a two-part hook device, each part having at one endca hook for. engaging one of sa d members, and at the other end an eye for 'engaglng the othermember, said ieyes being open forentering onto the memberv which they engage by: hooking move Vment in opposite directions, said two parts beingadapt ed to interlock with each other "in their said opposite hooking movement.

In theconstruction defined in claim 1 foregoing, the first mentioned hooks of said two vparts being at the interlocked position of the two parts, turned in the same direct1on for-engagement of: said first mentioned hooks of both of them with the firstmentioned member by one and the same bodily hooking movement of said two-part device.

, 3. Inthe structure defined in claim 1, the oppositelyopen-eyes of said two parts being helical and adapted to screw into eachother,

the interlocking of said parts being effected by so screwing said helixes together.

In testimony whereof I have hereunto set my hand at'Chic'ago, Illinois, this day of October, 1919. I U i r V CHARLES s. BURTON".
